Kitniyos

legumes, are those grains that can be cooked and baked in a fashion similar to chometz grain and yet are not considered, in the eyes of halacha, to be in the same category as chometz. Some examples are rice, corn, peas, mustard seed, and the whole bean family (i.e. kidney, lima, garbanzo, etc.). It is customary for Jews of Ashkenazic descent to refrain from eating kitniyos on Passover.
